Explanation:
Given :
A car retards uniformly at the rate of 5 m/s² and stops in 10 s.
To Find :
Initial Velocity of the car .
Solution :
\longmapsto\tt{Retardation\:(a)=-5\:{m/s}^{2}}⟼Retardation(a)=−5m/s
2
\longmapsto\tt{Final\:Velocity(v)=0\:m/s}⟼FinalVelocity(v)=0m/s
\longmapsto\tt{Time\:Taken=10\:sec}⟼TimeTaken=10sec
Using 1st Equation :
\longmapsto\tt\boxed{v=u+at}⟼
v=u+at
Putting Values :
\longmapsto\tt{0=u+(-5)\times{10}}⟼0=u+(−5)×10
\longmapsto\tt{-u=-50}⟼−u=−50
\longmapsto\tt\bf{u=50\:m/s}⟼u=50m/s
So , The Initial Velocity of car is 50 m/s .
Option c) 50 m/s is Correct .

Three Equations Of Motion :
v = u + at
s = ut + 1/2 at²
v² - u² = 2as
Here :
v = Final Velocity
u = Initial Velocity
t = Time Taken
a = Acceleration
s = Distance Travelled
